Stocks closed mixed Wednesday, with the tech sector dragged lower by shares of Apple and Twitter, as investors digested the latest policy decision by the U.S. Federal Reserve.

Apple's shares were down 6 percent at $97.82 after the tech giant reported its first revenue decline in 13 years, while Twitter slumped 16 percent to $14.86 after its revenue missed expectations.
